06 02 Exhaust temperature above 204 °F (96 °C)

What the control is telling you

Exhaust NTC reads vent temperature above 204 °F. Manual reset.

Applies to: TRX150

Likely causes

• Faulty exhaust sensor
• Blocked exhaust vent
• Scaled or dirty heat exchanger
• Faulty control or heat exchanger

Test and repair steps

1. Press Reset to clear the code.
2. Check the exhaust temperature sensor and make sure the connections are secure.
3. Check the sensor resistance. If it is zero, replace the sensor.
4. Compare the flue gas temperature with the reading on parameter 834. If parameter 834 is much higher, replace the flue sensor.
5. Check the exhaust vent for blockage.
6. If the problem continues, check the combustion chamber and clean if needed. Descale the heat exchanger.
7. If the problem continues, replace the control.
8. If the problem still continues, replace the heat exchanger.
